LinkedIn for a Whopping $1 Billion. Anyone?

Dave Wehner, the guy that was behind the recent AOL buys Bebo deal for $850 million, is the Managing Director of Allen & Co. Why would this be of any interest to you? Because the guy is rumored to be out pitching a LinkedIn venture capital round for nothing less than a whole big billion. Yes, $1 billion.
So far the Mountain View, California based company has raised $27.5 million over three rounds but if this turns out to be real, Allen & Co may be working on the most expensive private venture deal that we’ve heard of, lately.
Though rumors late last year said NewsCorpmay have been in talks with LinkedIn around an acquisition, no official papers were issued.
Honestly I don’t get it why a company like LinkedIn that have said publicly they will reach $100 million in revenue in 2008 would need funding so I suppose right now it’s nothing more than a rumor. Let’s see if we can find out more info in the days that will come.
